Keys is BlackBerry's new creative director for the BlackBerry 10 devices/software

BlackBerry may have thought it had an edge when it brought Alicia Keys onboard as the creative director for the new BlackBerry 10 devices/software, but the R&B singer-songwriter has already cheated on the brand with Apple.

Keys recently told The New York Times that she exclusively uses BlackBerry 10 devices now that she's the creative director of the line. However, it looks like Twitter busted Keys with an Apple device today.

Keys posted a tweet earlier today saying, "Started from the bottom now we're here!" However, the tweet was sent via the Twitter for iPhone app (as indicated in the screenshot below).

When the tweet started making its way around the Web, Keys posted yet another tweet saying, "What the h*ll?!!!! Looks like I've been hacked...I like @Drake but that wasn't my tweet :-("

While it's not so weird for celebrities to promote a product while using competing devices, this particular situation is a bit more interesting considering Keys has a paid position on the actual BlackBerry team; not just a promoter.

She should have just said that she accidentally used the iPhone app on her iPad (can be done with certain apps if you obtain them through iCloud or something)....Unless they actually expected her to use a BB PlayBook.
